ETEST® strips – the original gradient MIC strips – are considered a gold standard by many. It lives up to its reputation for reliably determining the on-scale Minimum Inhibitory Concentration (MIC) of antibiotics, antifungal agents and anti-mycobacterial agents. ETEST® is a predefined, stable gradient of 15 antimicrobial concentrations on a plastic strip. It is a simple, cost-effective tool that offers results when you need more precision than what automated or Kirby-Bauer antimicrobial susceptibility tests (AST) tests provide. ETEST® has an extensive range of over 100 antimicrobial references available in the following categories: Antibiotics, Antifungals, Antimycobacterials, and Antimicrobial Resistance Detection (ARD).

Trusted leader

The first gradient MIC strip of its kind, ETEST® continues to impress. Its well documented performance has solidified its position as the trusted leader in the gradient MIC strip market. In fact, ETEST® is the gradient MIC strip gold standard:

>4,000 scientific references from 50 countries

covering >2.9 million strains

representing more than 20 million data points

Versatile - The method of choice to supplement your primary AST system

Most clinical laboratories use commercially available automated AST systems, such as bioMérieux’s VITEK®, or disk diffusion as a primary means of AST. This is often adequate since most primary AST systems cover about 90% of AST needs. ETEST® is the method of choice to supplement the remaining ~10% of testing. It’s easy and economical to implement, and the strips’ stable antimicrobial concentration gradient carries an extended shelf-life of up to 5 years so you can keep rarely requested drugs on hand for rapid testing. Here’s how ETEST® fills the gaps beyond the breadth of primary AST usage:

*ETEST MBL IP/IPI and MBL MP/MPI are Research Use Only (RUO) products in USA
** ETEST AmpC, KPC and GRD are Research Use Only (RUO) products

Extended-range MICs spanning 15 two-fold dilutions

ETEST® provides full-range MICs spanning 15 two-fold dilutions for concentrations that are ideal for refining patient treatment in instances where routine AST methods are limited in one of the following ways:

"ETEST® is well established in our department. It has become a rapid and accurate tool for the determination of MICs in clinically relevant and urgent situations, e.g. for pathogens from blood cultures or CSF. It is also great to have in other clinical situations where it is important to know "how susceptible or resistant" the pathogen is. Also fro fungi, ETEST® is just fabulous. What a pain when MICs had to be determined by dilution methods!"

"ETEST® makes possible a standard method for testing a myriad of different types of organisms, almost "one-stop shopping". This has allowed laboratories with varying levels of expertise to perform antimicrobial susceptibility testing with enormous positive impact on patient care.

Having this technology available even in resource-poor areas of the world, has contributed to the dtection of resitances where such knowledge was previously unattainable."
